The SIFT method and lateral reading

You now have the pieces — context, reverse-image search, provenance, callbacks, claim-checking. This lesson ties them into one memorable routine used and taught by fact-checkers and libraries: SIFT, developed by digital-literacy educator Mike Caulfield. Four steps, one word.

• S — Stop. Before you read deeper, react, or share, pause. Notice your emotional state and remember that a strong pull to share is the signal to slow down. This step also means: do not get lost investigating one page for an hour. Stop, then move deliberately.
• I — Investigate the source. Before trusting the content, find out who is behind it. Are they a credible, established source, an anonymous account, a satire site, or someone with an agenda? A quick check of who is speaking reframes everything that follows.
• F — Find better or other coverage. Do not rely on the one post in front of you. Look for what other, ideally more trustworthy, sources say about the same claim or event. If a dramatic story is real, credible outlets will usually cover it; if only one obscure source has it, that itself is telling.
• T — Trace claims, quotes, and media to the original context. Follow the claim back to where it started. Find the original photo (reverse-image search), the full video, the actual study, the real quote in context. Misinformation thrives on stripped or altered context, and tracing restores it.

The engine underneath SIFT is lateral reading, the habit that separates skilled fact-checkers from the rest. Instead of reading down a suspicious page — studying its layout and its own claims about itself — you read across by opening new tabs and asking what the wider web says about this source and this claim. You spend little time on the page itself and quickly get off it to see what others report. A slick, professional-looking site can be completely unreliable; lateral reading is how you find that out fast rather than being taken in by presentation.

The beauty of SIFT is that it scales to how much the thing matters. A passing curiosity might get a ten-second Stop and a glance at the source. A claim you are about to share widely, or act on, earns all four steps. Same routine, adjustable effort.

Recap. SIFT is a four-step verification routine: Stop and notice the urge to react, Investigate who the source is, Find other and better coverage instead of trusting one post, and Trace claims and media back to their original context. Its engine is lateral reading — checking what the wider web says about a source and a claim rather than studying the suspicious page itself, because polish is not credibility. Scale the effort to the stakes, from a quick glance to all four steps, and you have one durable routine that pulls the whole course together.
